Medical historian Howard Markel traces the careers of two brilliant young doctors—Sigmund Freud, neurologist, and William Halsted, surgeon—showing how their powerful addictions to cocaine shaped their enormous contributions to psychology and medicine. He also examines the physical and emotional damage caused by the then-heralded wonder drug, and how each man ultimately changed the world in spite of it.
A narwhal tusk and a meticulous painting of a tulip might seem to have little in common, but they were among the wonders of nature and artifice displayed proudly in Renaissance collections of marvels. These early private collections, or cabinets of curiosity, ultimately led to the genesis of the modern museum. Biologist Kay Etheridge describes how this passion for collecting provided naturalists with centers of study and source material for their quest to find order in nature.
Using powerful sensors and computers—and even a repurposed particle accelerator—cultural heritage researcher Michael B. Toth and his colleagues in humanities and science mine everything from ancient manuscripts to fossils to lacquerware panels for new information about their content and creation. Past projects include the earliest known copy of work by Archimedes, Gutenberg and other early Bibles, and Muslim manuscripts.
Today more than 3 million people have pacemakers, with over 600,000 implanted yearly. Tom Choi, a pediatric cardiologist and electrophysiologist, and Carolyn Ramwell, an electrophysiology nurse clinician, discuss the fascinating past, present, and future of this small but essential lifesaving device, covering the experimental history of the modern pacemaker and defibrillator, the current applications of both, and the future implications posed by artificial intelligence and technological advances.
Complexity theory addresses the mysteries that animate science, philosophy, and metaphysics: how the teeming array of existence, from the infinitesimal to the infinite, is a seamless living whole and what our place, as conscious beings, is within it. Physician, scientist, and philosopher Neil Theise discusses this “theory of being,” one of the pillars of modern science, and its holistic view of human existence.
What makes for a long, happy, meaningful, and good life? The simple but surprising answer is relationships. It’s based on 85 years of work by the Harvard Study of Adult Development, which is still active. Marc Schulz, the study’s associate director and co-author of the new book The Good Life, Lessons from the World's Longest Scientific Study of Happiness, highlights findings from the Harvard Study as well as others that point to the critical role of relationships in shaping happiness and health.
For centuries, the coastal location and diverse landscape of Maine’s Acadia National Park have drawn people in search of beauty and inspiration. The region also has been a haven for scientists, whose written records, specimen collections, and oral histories have provided baselines for understanding environmental change. Author and scientist Catherine Schmitt shares the story of science in Acadia.
